[PATCH 3/5] block: nullblk: Set zone limits before revalidating zones

[Damien Le Moal]

In null_register_zoned_dev(), call blk_queue_chunk_sectors() and
blk_queue_max_zone_append_sectors() to respectively set the device zone
size and maximum zone append sector limit before executing
blk_revalidate_disk_zones() to allow this function to check zone limits.
